Function no_std_compat::arch::x86_64::_mm512_mask_rsqrt14_pd

pub unsafe fn _mm512_mask_rsqrt14_pd(src: __m512d, k: u8, a: __m512d) -> __m512d

🔬This is a nightly-only experimental API. (stdarch_x86_avx512)

Available on x86-64 only.

Compute the approximate reciprocal square root of packed double-precision (64-bit) floating-point elements in a, and store the results in dst using writemask k (elements are copied from src when the corresponding mask bit is not set). The maximum relative error for this approximation is less than 2^-14.
